My Favorite Model Has Become My older brother

Its weird, i dont really like step-sibling to lovers in the first place but this one just annoys me. The red hair guy she decides to date was perfectly fine. Him and the blond haired boy got along nicely when they were all friends, but then all the sudden hes lying and trying to compete with the blonde hair guy?? The author clearly sabotaged the character just to make the blond seem like a better option. Why even add him as a love interest if you were gonna do that, they were fine as friends.. and then they just gave like 3 chapters of them dating 1.4/10 wouldnt read again! (And overly cliche) 🙊

I hope i can see more brother sister manga like this
